` To all `whom it may concern:

and useful Improvements in' Stump-BurningAppliances, of vwhich the following is a y specification.

y The present invention pertains to a novel apparatus of the above type, primarily 'de\ signed to facilitate the burning of stumps,

. and itconsists in certain novel features and combinations of parts as set forth in the folour annexed claim.

lowing description, and succinctly defined in In the accompanying drawing,v 'whefin similar reference characters designate cori" responding parts throughout, Figure 1 shows in perspective an apparatus. embodying the features of our invention applied in operation on a stump, portions of some of the parts being broken away, and Fig. 2 is a longitudinal section of the combined air intake and fluid fuel appliance.

The a paratus, as shown, comprises a hood 1, constituting a combustion chamber, combined with an adjustable air intake tube 2, which serves as asupport for a fluid fuel appliance consisting of a burner 3, and a fuel chamber 11.' Hood 1, is conveniently of circular form in cross section and preferably provided with a fiat top Wall 1, and a fiari ing end portion as 10, terminating in an annular vertical base flange 11. Top l', as shown, is provided with a collar 12 fitting in a vent pipe or stack 13 of suitable length which has connection with the hood through an opening in top 1l bounded by the collar. Top 1..is further provided with a central opening normally closed by a cover 14 having a vsuitable handle forV yremoval when desiredto feed solid fuel to the hood. At opposite sides of cover 14 are interchangeablev circular closuresl, 16 tting freely in open- .ings of top 1, and provided with supporting flange extensions, as clearly ,shown 1n Fig. A1.

a tubular generating coil' provided with a A terminal tip 3 and extending about the an gular lower end portion of tube 2, communi cates witha ipe or assage way 5 extending within7 tu e 2, and connected Athrough a suitable shut off valve 6, 'with chamber 4,

outer end portion of tube 2. 'v

In applying the apparatus to a stump, solid fuel is placed about the stump or against one side thereof, and such protruding root portions as wouldvinterfere with a level seating of the hood are notched to receive flange 1 1, as indicated in Fig. 1. The applied fuel may now be ignited and the hood then placed in'position over the stump, or the hood may be rst placed and the re Athen started through the medium of burner 21. In the` latter event, valve 6 is opened with tube 2 suitably inclined for flow of fluid fuel from chamber 4 to the burner 3, where it is ignited upon escaping from the burner tip 3. The tube is then inserted in one of the side openings, in the top of the hood, to position the burner, as may befound desirable, and collar 15 applied to said opening. Tube 2 may now be shifted in collar 15 to carry burner 3 to various points or to direct the angular extremity of the tube for delivery of air to promote combustion of the solid material inclosed by the JOE SMITH.
